Terminal blocks are modular insulating blocks that hold two or more wires together. The factory uses terminal blocks to secure and terminate wires. In its most basic form, a terminal block consists of several individual terminals arranged in a long strip. Terminal blocks are best for grounding wiring.
The biggest advantage of terminal blocks is cost. They are cheaper compared to other types of connectors. Terminal blocks are also a time saver because the process of connecting wires is not as complicated as some others. Most well-equipped shops can easily connect wires using terminal blocks, just strip the wires.
Terminal blocks improve safety by grounding, isolating, and protecting other components in the circuit. Terminal blocks provide a finger-safe connection to prevent electrical shock. Moreover, the terminal blocks can also provide test points, thereby increasing the safety of the circuit.
They can then be installed using a screwdriver. They also ensure quick connect/disconnect, which aids in maintenance and troubleshooting. When using electricity, electrical junction boxes are used to connect electrical switches and receptacles to the power source.
